Road and registration taxes for your car

You pay the registration tax once, for a new or second-hand vehicle.

You pay the road tax every year. From now on, this matter falls under the authority of your Region, whether Flemish, Walloon or Brussels.

These taxes can count as professional expenses and be partially deducted. You deduct them according to your professional use, the date of purchase of your vehicle and its CO2 emissions:

1. Your professional use

30% of your journeys, excluding commutes between home and office, are for business purposes? 30% of your car expenses are deductible.

2. The CO2 emissions of your vehicle and its date of purchase.

🚗 You bought your car before 31/12/2017?

You deduct at least 75% or more. Find the case that corresponds to you in the table below:

- Petrol/diesel + CO2 emissions between 1 and 60 gr = 100% deductibility

- Petrol/diesel + CO2 emissions between 61 and 105 gr = 90% deductibility

- Petrol + CO2 emissions between 106 and 125 gr = 80% deductibility

- Diesel + CO2 emissions between 106 and 115 gr = 80% deductibility

Above these levels, you deduct 75%.

🚗 You bought your car from 01/01/2018?

Since 2020, you apply the following formula: 120% - (0,5% x fuel coefficient x CO2/km)

Do you have a diesel? The fuel coefficient is 1.

Do you have petrol? The fuel coefficient is 0.95.

Do you drive on CNG? The fuel coefficient will be 0.9 up to 11 fiscal horsepower, 0.95 beyond that.
